A Unified Verification Tool for C2PA & Blockchain

The Mintall C2PA Viewer shows the content credentials and blockchain record behind any certified asset, so anyone can check its provenance and ownership record in the open. No account required.

Open C2PA Viewer

What you can verify

The viewer surfaces concrete artifacts an agent or third party can check: credentials, signatures, and public references. No Mintall account required.

Blockchain explorer

If anchoring references are present, anyone can independently verify timestamps via a public explorer.

C2PA verification

Verify embedded C2PA metadata with tamper-evident signatures and extract normalized claims for downstream checks.

Reproducible evidence

Verification artifacts remain checkable by third parties and automation, without relying on private state.

One viewer, three jobs

Anyone can verify a Mintall-certified asset in the open, which is the point: proof that only works inside one vendor's app isn't proof.

Disputes & takedowns

Open a certificate in front of a platform, lawyer, or marketplace and show signed provenance, timestamps, and ownership without asking anyone to trust Mintall first.

How proof works

Partner & supply-chain checks

Buyers, distributors, and resellers can inspect the credentials behind product imagery before listing it, with no Mintall account required.

Verification at scale

Agent spot-checks

See what your agent consumes: the viewer renders the same C2PA manifests and registry anchors the Verification API returns.
